AASHTO Product Evaluation and Audit Solutions evaluated SIP-1111\u2122 through its Asphalt Mixture Recycling Agent DataMine program. The laboratory program compared a 45% RAP control mixture with the same mixture containing SIP-1111\u2122 at 3.2% by weight of virgin asphalt binder.<\/p>\n

The results show a useful balance for high-RAP design: the treated binder moved toward lower-temperature performance, cracking-test averages increased, and Hamburg rut depth remained below 4 mm after 20,000 passes.<\/p>\n

Low-temperature binder performance moved in the right direction<\/h2>\n

After one PAV cycle, the reported continuous binder grade changed from 69.7\/-23.6 for the control to 63.5\/-28.7 with SIP-1111\u2122. Delta Tc moved from -2.8\u00b0C to +0.5\u00b0C. After two PAV cycles, Delta Tc was -4.0\u00b0C for the control and -0.1\u00b0C for the treated binder.<\/p>\n

For a producer working with aged RAP binder, those shifts describe a wider low-temperature formulation window and less loss of relaxation behavior through the laboratory aging sequence.<\/p>\n

Cracking-test averages increased<\/h2>\n

The Overlay Test average increased from 225 cycles for the control to 300.3 cycles with SIP-1111\u2122. IDEAL-CT Index increased in both the short-term and long-term conditioned comparisons.<\/p>\n

Hamburg performance stayed tight at 20,000 passes<\/h2>\n

Hamburg rut depth at 20,000 passes was 3.1 mm for the control and 3.5 mm for the SIP-1111\u2122 mixture. The 0.4 mm difference shows the high-temperature side of the softening response while both reported rut depths remained compact.<\/p>\n

The binder MSCR result follows the same pattern: Jnr 3.2 increased from 1.4 to 4.9 kPa-1<\/sup>. Producers can use the full result set to tune dosage, virgin binder, aggregate structure, and any polymer package around the project\u2019s climate and traffic requirements.<\/p>\n

What PEAS gives an asphalt buyer<\/h2>\n

The DataMine report puts binder and mixture measurements from an AASHTO evaluation program in one place. It gives agencies, contractors, and mix designers a common technical starting point for project-specific trials and balanced mix design.<\/p>\n

AASHTO PEAS evaluation records test results. Product approval, qualified-product-list placement, and specification decisions remain with the responsible agencies and their established processes.<\/p>\n
